The invention relates to the technical field of new energy wireless charging, in particular to a wireless charging system based on three ports, which realizes energy conversion under four conditions of photovoltaic to load, energy storage battery to load, simultaneous power supply of photovoltaic and energy storage battery to load, and photovoltaic to energy storage battery by controlling a switch tube. One side of the circuit structure is composed of a full-bridge inversion structure and a half-bridge inversion structure and comprises six switching tubes and two alternating-current switches, the secondary side of the circuit structure is composed of a rectification structure and a DC-DC converter, and the circuit allows two power supplies, namely a PV and a storage battery, to share a resonance network. According to the invention, by establishing a three-port wireless charging system integrating photovoltaic power generation, an energy storage battery and a load, solar power generation and a wireless charging technology are combined, a novel green and environment-friendly charging system is designed and developed, on one hand, actual requirements of some special application occasions can be met, and the application field of the wireless charging technology is expanded; and on the other hand, energy conservation and environmental protection are achieved.

    本发明涉及新能源无线充电技术领域,具体为一种基于三端口无线充电系统,通过控制开关管分别实现光伏到负载、储能电池到负载、光伏和储能电池同时向负载供电、光伏到储能电池等四种情形下的能量转换;电路结构一侧由一个全桥和一个半桥逆变结构组成,包含六个开关管和两个交流开关,二次侧由整流结构和一个DC‑DC变换器组成,电路允许PV和蓄电池两个电源共用一个共振网络。本发明通过建立光伏、储能电池、负载一体的三端口无线充电系统,将太阳能发电与无线充电技术相结合,设计开发一种新型绿色环保充电系统,一方面能满足一些特殊应用场合的实际需求,拓展了无线充电技术的应用领域;另一方面具有节能环保的优点。
